AnotationEnhanced contact endoscopy (ECE) is one of the new advanced endoscopy methods. It uses a combination of magnifying optics with special imaging modes such as Narrow band imaging (NBI) or IMAGE1S. These methods are now considered the golden standard in the early diagnosis of tumorous lesions of the head and neck mucosa. They improve imaging of mucosal vascularization, which forms a specific pattern which is based on the character of the lesion. However, these methods are subjective, and despite many efforts to objectify the findings using various classification systems, still dependent on the investigator's interpretation. Today, advanced endoscopy methods are common part of ENT clinics. They are used by inexperienced investigators who are much more likely to misinterpret the findings. Incorrect interpretation of the examination may lead to a delay in the patient's therapy and may lead to the need for more radical, devastating therapy. The interrater variability is marginalized in the available studies, and satisfactory study focusing on the differences between inexperienced and experienced investigator is non-existent. There is also no comparison of the error rate of inexperienced and experienced examinator in white light, IMAGE 1S and ECE. The aim of the study is to conduct a comprehensive study focused on the interpretation of the results of these examinations at 3 levels of expertise - a medical student, a resident and an experienced laryngologist.
